According to TechCrunch, Apple had originally planned to announce some improvements to Maps during WWDC but one source claims that none of the new features were ready to show off at WWDC and many developers who had been working on them have actually left the company. The source also doesn’t sugarcoat anything when it comes to laying blame on Apple management.

“Mostly it was failure of project managers and engineering project managers, tasks were very badly planned, developers had to switch multiple times from project to project,” the source says, while a separate source chimes in to say “that planning, project management and internal politics issues were a much more significant contributor to the failure to complete projects than developers leaving the group.”

Apple is still making key acquisitions to improve Maps, of course, but for the time being it looks like you shouldn’t expect major improvements to it anytime soon.
